Four row cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load. The friction roller and ring guard is small, be applicable to the high speed rotation. May according to the ring presence of guard, NU, NJ, NUP, N, NF, such as single bearing, and NNU, NN etc. Double row bearings. The bearing inner ring and outer ring is separable structure. No guard of cylindrical roller bearing inner ring or outer ring, internal ring and outer ring can be to relative axial movement, so can be used as free end bearing. The one side of the inner ring and outer ring with double guard, on the other side of the ring has a single guard cylindrical roller bearing, can withstand a certain degree of axial load in one direction. General use of stamping steel cage, cage or copper alloy car system. But there are also part of the use of polyamide forming keep frame.

Application

Four row cylindrical roller bearings Mainly bear radial primarily diameter, the axial load. Bearing capacity depends on the Angle of the outer ring raceway, the greater the Angle, the greater the carrying capacity. The separated type bearing is a bearing, according to the bearing the number of columns of the scroll body can be divided into single row, double row and four row circular cone roller bearings. Single row tapered roller bearing clearance to users in the installation adjustment; Double row and four row circular cone roller bearings clearance has according to user requirements for a given when the products leave the factory, not the user. Four row cylindrical roller bearings With conical inner ring and outer ring raceway, the tapered roller are arranged in between. All projection line on the surface of the cone axis bearing the same points together. This design make the taper roller bearing is especially suitable for composite (radial and axial load. Bearing axial load capacity is mostly determined by the contact Angle alpha; Alpha Angle is larger, the higher axial load capacity. Angle size by calculating coefficient of e; E value, the greater the contact Angle, the greater the bearing axial load of the greater applicability.

Four row cylindrical roller bearings are usually separated type, namely by inner ring with roller and cage components of cone inner ring components can be installed separately with cone outer ring (outer ring).
